UNITED STATES PATENT. OFFICE. CHARLES arm NEW YORK, n. Y.

To all whom it may concern Beit known that 1, CHARLES J. Knrrnnn, acitizen of the United States, residing at New York, borough ofManhattan, county and State of New York, have made a new and usefulInvention in Dough-Cutting Ma-.

chines, of'which the following, is a specification.

My invention is directed to improvements in machines for automaticallycuttingdough into parts of equal volume and weight and will be fullyunderstood by referring to the accompanying drawings, in which,

i eiid of the driving shaft S provided with a driv'i pulle P and afeeding worm or I sai shaft being j'ournaled in a cross-bar J i securedin the interior of the bod portion A.

e upper portion of the body partA is secured by-earsor-lugs B todownwardlyextending parts of the cuprshaped wall bracket 0 whichparts-also act as ournal bearings for two rotary driving shafts s, 8,provided at-their lower ends with bevel gear-wheels g, g,connectedthroughintermeshing gearwheels 9 ,9 one with a rotary shaft 6:provided with an enlarged head or hub M and detachable cap M supportingone or more detachables teel sprin arms L adapted to carry at the outeren or ends one ormore cutting knives K, and'the other with .a shaft 8supported by the legs F F and carrying a delivery belt drum P adapted tocarry one end of a delivery belt E moving in 2. ,The

the direction of the arrow, Fig. lower part of the body po'rtionA is ofcurvilinear form and is provided with a detachable discharge nozzle Nsecured thereto by bolts or other detachable means, the arrangementbeing such that any sized nozzle may be substituted, dependent upon thevolume of dough it is deemed to eject. v

Pt is a delivery roll journaled on one'side in an extension Q of the leother side in a similar extension of one of the F and on the legs F, thefunction of said roll bein to rean inclined lug a adapted to be adjustedwith relationto a corresponding lug 0 carried at the outer end of thesnap actin' cutting knife K so as to thereby vary the re ativedlstancebetween said parts,as will be-more particularly described-in connectionwith the descriptibn'of the mode of operation.

Referring now. to Figs. sand 5 I will describe more particularly themanner of supporting the spring arms L, L which carry the cutting knivesK, Mbeing as before 1ndica-ted a hub secured directly to the outer endvof the shaft 8 In the outer face of this hub is cut one "or more slotsor notches m, m,

k, lcyafter which the nuts t, cured so as to give to 'the rubber ringsthe provided with curvilinear faces so arranged that when the springarms L, L, L are secured, to the hub and inthe notches by thescrews '0,o, and after the cap M is secured in position by the screws f, f, theinner ends of said arms will lie within the notches, so that when theshaft is rotated from left to right the spring armsL will curve aroundvided with a splinegroo ve adapted to fit either of said splines. is isa. set-screw for securing this body part P at any desired posi-, tion onthe shafts s, s, with relation to the cone-shaped pulley P preferablymilled on its surface. R, R are soft rubber rings cone.- shapedinteriorly and exteriorly, as shown, and p, p are face plates providedwith centralopenings for fitting over-the body part 2 and the shaft 8,w, 10, being bolts and t, t, screw-nuts for firmly gripplng saidfaceplates together in such manner as to vary the relative exteriordiameters of the soft rubber cone-shaped rings B. As many of these ringsof different diameters and bodyparts, etc. are provided for both of theshafts's, s as may be deemed necessary to vary thesize of the loaves orparts of dough an'd the corresponding rate of speed with which thedelivery belt E shall be run, the exterior diame- 4 ter of the rings Rdeterminin such speed and the corresponding variable iameters of thecone-shaped pulley P varyingthe speed, as will be appreciated byaninspection of Fig. 1.

The Q eration is as follows-'The body part A 1s filled with dough andthe rim s R, R of the desired diameter are secured in place upon the twoshafts .9, .9, by set-screws t, are 'firmly sedesired frictional bearingwith the coneshaped driving pulleyP. The machine is then set in motionthrough the agency of the pulley P rotating the shaft S in the directionof the curved arrow, screw S forces the dough forward out of the nozzleN and the two driving shafts s,- 8, drive respectively, one the snapacting E. As the driving shafts is rotated the knife K is also rotateduntil the lug 0 at the outer end thereof comes into mechanical pieces ofdough to shafts s;

. the extension Q,

see Fig. 1. The

.adjustability of all of the parts ,paratus variable sized releasedthereby imparting to the knife a sudden snap acting movement, instantlysevering the dough as .the knife passes the of the screw S bears a fixedratio to the speed of the knife operating apparatus, so that each pieceof dough thus cut off must be identically the same in volume and weightas the piece precedingit. The adjustablhty .of the arm T and lugs a and0 also facilitate I a more perfect and delicate operation of themachine, for the reason that when the snap acting cutting knife isadjusted rad1ally.1t is found necessary to effect the adjustment ofthese parts to prevent-the cutting edge of the knife ,from coming intocontact with the material as it emerges from the nozzle N.

. It is also obvious that the speed of the delivery belt E is varied byits cone-shaped driving ring R to correspond with the varia tion inspeed of the knife cutting roll. As shown in Fig. 4 there may bearranged any number of knife supporting springs so-that for eachcomplete revolution of the hub M there will be out four pieces ofdough,'each the, exact duplicate. of'its predecessor; or, if preferred,twoknives may be used, said kmvesbeing located diametrically opposite toeach other. By using either a single knife carried by a single springsupporting arm L or arranging the knives; thus supported in pairs inthemanner shown in Fig.

4, I may vary the size of the loaves in multiple and by varyingthe sizeof the rings R, R for both the knife cutting and delivery apparatus andalso the adjustment of arm T and lugs. 0 and a, or by varying the radialto the baker. On the adjustment of the knife or knives through theagency of the radial sliding spring arms L, L, L and set-screws 'v, c,'v, and ,the lateral adjustment of the arm T supported by I may vary thesize of the loaves as desired, so that the will be a tingequa sizedrolls or parts of any desired SIZG. cutting. knife K and the other thedelivery belt It is also obvious that by reason .of the of the aploavesmay be produced and variable speed feed-of the material efi'ected, andthat the machineis particularly we lladapted, by reason of itsadjustability, to effect the instantaneous severmg of the dough nomatter what may be its viscosity, a feature of utility which is not Iapparatus, it parent, 1s at once capable of cutrequired in machinesforcutting butter or analogous substances. 7

It will also be noted that by reason of the snapping action of thecutting knives I am enabled to cut the dough clean and instantaneouslywithout interfering with its flow from the nozzle N, thereby giving toall parts of the severed loaves or pieces an exact similarity of form,size and weight.

I am aware that it hasheretofore been proposed to mold and cut butterand similar substances which change their density at differenttemperatures by a machine having a cylindrical chamber, a spiral -orscrewthreaded feeding device located therein and driven by a rotaryshaft intergeared with a second shaft which carries a yielding knifeadapted to be momentarily held before it reaches the outlet at themolding or forming end of the chamber, and in such manner as to besuddenly snapped past the same, and I make no claim broadly to such astructural apparatus.

Having thus described my invention what I claim and desire to securebyLetters Patent of the United States is' 2.
